I created an Electron app, renamed Electron.app to Trader.app, also renamed binaries and Helpers. Of course, I edited all related plists. Everything worked fine.

Now I want to rename my app again. From Trader.app to Traderno.app (just for example). I renamed Trader.app to Traderno.app, renamed executable file from Trader to Traderno. Also renamed Bundle display name, Executable file and Bundle name to Traderno in Info.plist. Then I changed Bundle Identifier to some.text.traderno in Info.plist. I decided not to rename Helpers. Hope it’s not necessary. Then I performed codesign.

Additional information. The problem actually happens when I try to change CFBundleName at Info.plist. After this and the following codesign app crashes as I described above. Maybe I forgot to change something else?
